The problem is that the new glibc needs libgcc_s.so.1 for exceptions
handling, which needs in turn libc.so.6. Linking with -lc_p means the
glibc is linked statically, while it is also linked dynamically via
libgcc.

The solution is to link with -static-libgcc -lc_p.

I will add a README to the libc6-prof package to explain how to use it.
